To determine the correct IUPAC name for the given compounds (MnO3 and N2O), we need to follow the rules set by the International Union of Pure and Applied Chemistry (IUPAC).
Compound 1) MnO3:
1. Identify the elements present in the compound:
- Mn represents the element manganese.
- O represents the element oxygen.
2. Determine the oxidation state of the metal (Mn):
- To determine the oxidation state of manganese, we need to consider the overall charge of the compound. In this case, since there is no further information provided, we assume the compound has a neutral charge.
- Oxygen typically has an oxidation state of -2, so we can calculate the oxidation state of manganese based on this information.
- With three oxygen atoms, the total charge contributed by oxygen is -2 x 3 = -6.
- Since the compound is neutral, the sum of the oxidation states should be zero.
- Therefore, the oxidation state of manganese (Mn) will be +6.
3. Write the name of the compound using the appropriate prefixes and Roman numerals:
- Since the compound contains a transition metal (manganese) that can exhibit variable oxidation states, we need to indicate this using a Roman numeral in the name.
- First, we start by writing the name of the metal (manganese).
- Next, we write the oxidation state of the metal using Roman numerals inside parentheses. In this case, since the oxidation state of manganese is +6, we write it as "(VI)".
- Finally, we write the name of the non-metal (oxygen) and add the appropriate prefix to indicate the number of oxygen atoms.
- The prefix for three oxygen atoms is "tri".
- Consequently, the IUPAC name for compound 1) MnO3 is "manganese(VI) trioxide".
Compound 2) N2O:
1. Identify the elements present in the compound:
- N represents the element nitrogen.
- O represents the element oxygen.
2. Determine the oxidation state of the elements:
- In this case, since no oxidation states are provided, we assume the compound has a neutral charge.
- Oxygen typically has an oxidation state of -2, so we can calculate the oxidation state of nitrogen based on this information.
- With two nitrogen atoms and one oxygen atom, the total charge contributed by oxygen is -2.
- Since the compound is neutral, the sum of the oxidation states should be zero.
- Therefore, each nitrogen atom must have an oxidation state of +1.
3. Write the name of the compound using the appropriate prefixes and Roman numerals:
- Since the compound does not contain a transition metal, there is no need to use a Roman numeral in the name.
- First, we write the name of the non-metal (nitrogen) and add the appropriate prefix to indicate the number of nitrogen atoms.
- The prefix for two nitrogen atoms is "di".
- Next, we write the name of the non-metal (oxygen) and add the appropriate prefix to indicate the number of oxygen atoms.
- The prefix for one oxygen atom is "mono".
- Consequently, the IUPAC name for compound 2) N2O is "dinitrogen monoxide".
